Write operations are not allowed in read-only mode

在使用hibernate时,我遇到了这样一个问题

Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.

后来研究发现，这是因为

<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>

使用了OpenSessionInViewFilter所致，只需要使用AOP将事务管理起来就可以解决该问题了

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="del*" propagation="REQUIRED" />
<tx:method name="modify*" propagation="REQUIRED" />
<tx:method name="change*" propagation="REQUIRED" />
<tx:method name="*" read-only="false" />
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="mypointcut" expression="execution(* service.*.*.*(..))" />
<aop:advisor pointcut-ref="mypointcut" advice-ref="txAdvice" />
</aop:config>
